Happened to pick up a piece I hadn't worn in a while that has a stiff bezel action and was turning it to loosen it up a little as is my habit when I wear it. Hoping one day it won't take major effort to set the dive bezel time. It occurred to me. Is a dive bezel considered a Feature of the case or a complication? Are complications only part of the movement or are things like a Canteen crown considered complications? Just semantics but I was curious? Sorry to take so long but I thought I'd explain the question a little.
